PHP API: Can anyone see this code and error message?

Hi,

I'm coding a PHP script to create a document (STEP 1) and link it to an existing task(STEP2) and add a URL shortcut to the document.(STEP3).

Step 1 and 2 are ok, but Step 3 gives me an error and I cannot find any PHP API help except from here.

Here are my code and error message in the web page.

Thanks for your help in advance!
